First, an overview 
 HDGC3530 three-phase power quality analyzer is the reference to "GB/T14549-93 power quality utility grid harmonic GB IEC 61000-4-31 A, class standards of design and manufacture, detection and analysis of the quality of grid operation dedicated handheld Product instruments. Power operation of harmonic analysis and power quality data analysis, while the impact on power in the process of starting and stopping of large electrical equipment monitoring the entire process. Equipped with large-capacity memory, long-term data acquisition testing the power grid, with PC applications software, upload the collected data to a computer to facilitate a variety of analysis. 
 Second, the functional 
 Basic measuring function: 
 Measurement of voltage, current, frequency, and record trends. 
 Harmonic measurement function: 
 1 to 50 harmonic measure three-phase four-wire (three voltage and current), and its total harmonic distortion. And record one of the first harmonic trend. 
 Power measurement function: 
 Measure three-phase four-wire electrical system in three-phase active power, apparent power, reactive power, power factor and record the trend of the three-phase active power.

 Monitoring and recording functions: 
 Monitoring and recording function can be three-phase four-wire power system three-phase voltage, phase current, neutral current (THD, 1 to 25 harmonics), the current harmonics (THD, 1 to 25 harmonic ), unbalanced three-phase, active power, power factor and other parameters of the long measurement record. 
 Digital oscilloscope function: 
 Can detect three-phase four-wire electrical system voltage and current waveforms changes, and can record a moment of voltage or current waveform. 
 Third, the design features 
 Small size, light weight and easy to carry 
 High-performance lithium batteries for a long time supply 
 Complete three-phase troubleshooting tool: the actual measurements for each power system parameter: voltage, current, frequency, power, power consumption (energy), unbalance and flicker, harmonics and inter-harmonics to capture sudden drop in like a sudden jump in These events, transients, interruptions and rapid voltage changes. 
 Fourth, the typical application 
 ① front-end troubleshooting: the screen displays the failure of rapid diagnosis, allowing the system to resume normal work 
 ② predictive maintenance: to detect and prevent power quality problems in the event of a lockout before 
 ③ quality of service: the user to introduce the line to check the power quality 
 ④ long analysis: detection of difficult to find or intermittent failures 
 (5) load research: check the electrical system capacity before the increase in load 
 ⑥ energy assessment: energy consumption before and after the transformation of quantitative assessment to prove the effect of saving equipment
